Designing an arcade machine for high-humidity environments requires careful planning to ensure longevity and performance. Here are the key considerations:

1. Material Selection: Use moisture-resistant materials like stainless steel, powder-coated metals, or marine-grade plastics to prevent rust and degradation.

2. Corrosion Protection: Apply anti-corrosion coatings on metal components and use sealed connectors to protect internal electronics.

3. Ventilation and Sealing: Incorporate proper ventilation to reduce condensation while sealing sensitive areas to block moisture ingress.

4. Component Protection: Opt for waterproof or humidity-resistant buttons, joysticks, and PCBs to avoid malfunctions.

5. Regular Maintenance: Design for easy access to internal parts for cleaning and drying to prevent mold and electrical issues.

By addressing these factors, arcade machines can withstand high-humidity conditions and deliver reliable performance.
